    Software center update stalled ? Snap ?

    As a usual software update was near complete the notification stalled on 'snap ?'

    I then noticed that the software center had gone.
    can't seem to install it as it appears to be locked
    After some hunting for a solution i'm guessing that snap is a new software center ??

    Anyway I ... this is where I am..

    Code:
    :~$ snap changesID   Status  Spawn               Ready               Summary
    43   Error   today at 12:23 BST  today at 17:41 BST  Install "snap-store" snap from "stable/ubuntu-20.04" channel
    :~$ snap abort snap-store
    error: cannot find change with id "snap-store"
    :~$
    If I could re-initiate the whole update that would be great ???? as I fear other upgrades included may have also been compromised.. but I 'think' Ubuntu Studio thinks its still installing snap ??? so not allowing me to freshly install it ?

    erm..
    help .. please.

    Re: Software center update stalled ? Snap ?

    There have been a few things happening regarding the Ubuntu Software Center store in Ubuntu 20.04 that may apply to Ubuntu Studio.

    1) Ubuntu Software Center was a re-branded Gnome Software. 2)The developers brought in a Snap Store to install snaps. 3) The Snap Store had a lot of work done to it and it became Ubuntu Software with the re-branded Gnome Software being removed. There was a period when my 20.04 system had two Ubuntu Software apps each with its own icon as well as a Snap Store icon. At present this system does not have a Ubuntu Software icon of any kind. They have both been removed. It has a Snap Store that should have been re-labeled Ubuntu Software.

    To sort your problem out you could load into Recovery Mode at the Grub menu. We get to it by selecting Advanced options for Ubuntu. At the Recovery menu select Network to establish an Internet connection. When back at the Recovery menu select Root Shell prompt and at the command line type

    Code:
    apt update
    apt upgrade
    The system should update/upgrade. When it is finished type

    Code:
    exit
    to return to the Recovery menu and the select Resume to finish boot the OS. You should end up at a desktop running in basic video mode. Shutdown and reboot to load a video driver.

    Re: Software center update stalled ? Snap ?

    I may not completely understand your problem. Maybe some background helps.

    There are two ways in which software gets packaged for Ubuntu. Two main ways, there are some others. There are deb packages and snap packages. They both have their own set of tools to install or remove them. Deb packages use dpkg, apt and synaptic, snap packages use snap. They are mostly independent, except that the tools that handle snap packages come from deb packages themselves, some higher-level tools (like Ubuntu Software or whatever it's called now) can interact with both sets of tools to handle both types of packages (easy and integrated, but it causes confusion) and some deb packages trigger the installation of snap packages. All important stuff is in deb packages. I've never had any snaps on my system, so I don't know them very well.

    If you're worried that your updates to ordinary deb packages are compromised, run this:
    Code:
    sudo apt update
    sudo apt upgrade
    That will check for upgrades for your deb packages, then download and install those upgrades. If it reports no errors, your deb packages are fine. I'll leave it to someone else to check-up your snaps.

    As long as you don't start partitioning or reinstalling Ubuntu (or running stupid commands), your data are safe. As long as you've got backups (you should), your data are safe too.

    Snap only runs in the terminal. It's the management tool for Snap applications. Try running 'snap' in the terminal for more information.

    I don't use Ubuntu Studio, so I'm not sure what it provides you for finding software. It could be called 'Ubuntu Software' or just 'Software'.

    Here on my 20.04 the software store is good old gnome-software, "ubuntu-software" is a dummy package that points to the same thing, the snap integration is provided by gnome-software-plugin-snap, so in the software store you find both snap and apt packages (also there is gnome-software-plugin-flatpak if you want flatpak pages to be accessible from software store) I suppose you can install gnome-software and plugin(s) on ubuntu studio if they are not already installed.
